RadListControl Move item

[Carol Watson]

At design time I can Add items to the Items Collection and change the order they are displayed.

Is it possible to do this at run time, if so how.  

It is possible to do this with a list that is bound to datasource?

Thanks

Hello Carol,

When using the control in data bound mode you should not manipulate the items directly (e.g. you should not call the Insert, Add or Clear methods of the Items collection).

I would suggest that you prepare the items in the DataLayer (for example, sort them).

Do not hesitate to contact us if you have other questions.

Hi,

   If we through operate the data source(for example, remove and insert,),so that we can change the order they are  displayed (Up and down).However,  The selected Item is always the first Item in RadListControl visible region because of the vertical scroll bar ---what is not expected.

   How to do?
   Thanks!

Hello Ajing,

Thank you for contacting us.

As far as I understand, you want to remove the selected item in order to modify the DataSource.
To achieve this you can set SelectedIndex to -1 before modifying the data source - this will clear the selected item.

I hope this helps.

All the best,

Hi,

How to remove a particular item from RadDropDownList?

for eg., I can Add like, rddl_Items.Add("Car")

IN Vb.Net, I can remove like, rddl_Items.remove("Car")

Please help.

Thanks in advance

Hi Arun,

Thank you for writing.

You can directly access the Items collection and use either the Remove or RemoveAt methods. The first method received a RadListDataItem as a parameter and the second receives an index.

I hope this information was useful. Should you have further questions please do not hesitate to write back.
